Solve for x ill give brainlest!!!

butalik [34]

Answer:

$x=-9$

Step-by-step explanation:

$36^{x-3}=1296^{x+3}\\(6^2)^{x-3}=(6^4)^{x+3}\\2(x-3)=4(x+3)\\x-3=2x+6\\x+6=-3\\x=-9$

You read 4 1/2 pages in 12 minutes. at the same rate, how many pages could you read in an hour?

nignag [31]

Answer:

22.5 pages

Step-by-step explanation:

First divide the page number by the minutes it takes to read them to find pages per minute-

4.5 / 12 = .375

Then take that number and multiply it by the minutes in an hour-

(.375) (60) = 22.5

22.5 pages in one hour.

what is the slope of a line that is perpendicular to the line that contains points (5,4) and (-7,9). explain please

Luba_88 [7]

Answer:

$\frac{12}{5}$

Step-by-step explanation:

First find the slope of the line containing points (5,4) and (-7,9). To find the slope use the formula $\frac{y_{2} -y_{1}}{x_{2}-x_{1}}$ . Putting those values in, you have

$\frac{9-4}{-7-5}$

Simplify

$\frac{5}{-12}$

$-\frac{5}{12}$

Then, to find the slope of the line perpendicular to that, find the negative reciprocal.

$\frac{12}{5}$

A random sample of 77 fields of durum wheat has a mean yield of 27.427.4 bushels per acre and standard deviation of 5.755.75 bus

xz_007 [3.2K]

Answer:

[ 21.79, 33.0 ]

Step-by-step explanation:

Given:

Sample size, n = 7

Sample mean, μ = 27.4

Standard deviation, σ = 5.75

Confidence level is 99%

also, population is normal i.e normally distributed

Thus,

Confidence interval = μ ± $z\frac{\sigma}{\sqrt n}$

For confidence level of 99%

z-value = 2.58

Therefore,

Lower limit of Confidence interval = μ - $2.58\times\frac{5.75}{\sqrt{7}}$

Lower limit of Confidence interval = 27.4 - $2.58\times\frac{5.75}{\sqrt{7}}$

Lower limit of Confidence interval = 21.79

Upper limit of Confidence interval = μ + $2.58\times\frac{5.75}{\sqrt{7}}$

Upper limit of Confidence interval = 27.4 + $2.58\times\frac{5.75}{\sqrt{7}}$

Upper limit of Confidence interval = 33.00

Hence, confidence interval = [ 21.79, 33.0 ]
